Why Validate Your ZUGFeRD Invoices?
Sending a non-compliant ZUGFeRD invoice can lead to rejected payments, delayed processing, and compliance penalties. Our validator catches schema errors, missing mandatory fields, and business-rule violations before you send — ensuring your invoices are accepted the first time by any ZUGFeRD-capable system across Europe.
Frequently Asked Questions
What does ZUGFeRD validation check?
Our validator checks the embedded XML against the ZUGFeRD 2.1 specification, verifies PDF/A-3 compliance, validates the XML schema (XSD), and runs Schematron business-rule checks defined by the European Norm EN 16931.
Which ZUGFeRD profiles can be validated?
We validate all ZUGFeRD 2.1 profiles: Minimum, Basic WL, Basic, EN 16931 (Comfort), and Extended. The validator automatically detects the declared profile and applies the correct rule set.
Is my invoice data kept private?
Absolutely. Your files are processed in memory and never stored on our servers. All communication is encrypted via TLS, and files are discarded immediately after validation.
What do I get in the validation report?
You receive a detailed report listing every error, warning, and informational notice — including the exact XML path, rule ID, and a human-readable explanation so you can fix issues quickly.
